<p>So I'm trying to decide between CMU and UCLA which I both got into for Chemistry, but I think I might like to switch to Chemical Engineering early on in college to better facilitate getting an MBA. However, UCLA is ranked much better than CMU for Chemistry and Carnegie Mellon is ranked much better than UCLA for Chemical Engineering. Switching between the two would require changing schools at CMU, so is it very difficult to do this at CMU? Also if I decided I wanted an undergrad business degree at CMU would it be too difficult to switch to Tepper?</p>
